Don’t miss the signs

A fellow was stuck on his rooftop in a flood. He was praying to God for help.
Soon a man in a rowboat came by and the fellow shouted to the man on the roof, “Jump in, I can save you.”
The stranded fellow shouted back, “No, it’s OK, I’m praying to God and he is going to save me.”
So, the rowboat went on.

Then a motorboat came by. “The fellow in the motorboat shouted, “Jump in, I can save you.”
To this the stranded man said, “No thanks, I’m praying to God and he is going to save me. I have faith.”
So, the motorboat went on.

Then a helicopter came by and the pilot shouted down, “Grab this rope and I will lift you to safety.”
To this the stranded man again replied, “No thanks, I’m praying to God and he is going to save me. I have faith.”
So, the helicopter reluctantly flew away. Soon the water rose above the rooftop and the man died.

He went to Heaven. He finally got to discuss this whole situation with God, at which point he said, “I had faith in you but you didn’t save me”. I don’t understand why.

To this God replied, “I sent you a rowboat and a motorboat and a helicopter, what more did you want?”
